FENDER FOR VESSELSs SPECIFICATION forming part of Letters Patent No. 461,? 59, dated October 20, 1891.

- Application filed December 6, 1890. Serial No. 373,751. (No model.) I

T on whom it may concern.-

Be it known that I, JAcoBUs THEODOOR CHRISTIAAN KOCH, residing at 50 Egelantiersgracht, Amsterdam, in the Kingdom of Holland, have invented new and useful Improvements in Fenders or Cutters for Vessels for Preventing the Disastrous Consequences of Collisions, of which the following is a specification.

The object of my invention is to provide effective fenders by means of which the injurious effects of vessels colliding may be materially lessened.

The fenders are of elastic material in the main, and are designed to take up much of the effect of the blowin the event of collision and to distribute the effect over a large surface.

The invention consists of the novel construction and arrangement, as hereinafter particularly described, and defined in the claims.

Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sideview of a vessel having my improved fenders applied thereto. Fig. 2 is a front View thereof. Fig. 3 is a horizontal section of a fender'ada'pted to the bow of a vessel. Fig. 4 is a similar view of a slightlymodified construction of such fender, and Fig. 5 is a transverse vertical section of a fender adapted to the side of a vessel.

In the various forms my improved fenders have the common feature of being elastic, and also have a rigid frame, to which the elastic cushion is secured, whereby body is given to the latter. 1

The fenders shown in Figs. 3 and I are adapted to the bow of a vessel, two or more of such fenders being employed in practice, as desired. These fenders consist each of an elastic cushion A and a rigid frame B, of metal or wood. The main portion or body a of the cushion A is of highly-elastic indiarubber, over which is secured a covering a, of metal or other suitable material, and over the covering a a facing 6L2, preferably of cork, is placed, the whole being inclosed in an outer wrapping a of rope net-work.

The frame 13, of metal or wood, consists of a face-plate b, to which the cushion A is sodivergent arms b 6' project to conform in a measure to the lines of the bow. directly in the rear of the cut-water. Vebs b extend from the plate I) to the arms I) for strengthening the fender. On the inside of the arms 1) rubber pads are secured for lessening the injury to the vessels bow. In the form shown in Fig. 3 these pads 19 are of flat form and extend along the length of the arms.

In the form shown in Fig. 4 the pads b consist of blocks having a rounded outer surface, the arms I) being formed with corresponding recesses for receiving such blocks. In this figure, also, the arms I) are shown as diverging somewhat from the lines of the vessel, the object of which is to further lessen the danger of the arms piercing the vessel in the event of a collision.

The fenders for the sides of the vessel are formed essentially the same as those above described, in that they consist of a rigid frame and an elastic cushion. The cushion A A of the side fenders are united to a common frame B at each side of the latter and are faced with cork, &c., similarly to those above described. The frame B is by preference formed of two superimposed I-beams b firmly bolted together. 7

The fenders are secured in place on the vessel in any suitable manner, preferably by the means shown, which consists in the case of the bow-fenders of guys 0, which are suitably secured at one end on deck, and at the other end are fastened to eyes I), formed in the arms b.

The side fenders are secured to suspension ropes (l, which are fastened to hooks f or other devices on the fendersg' jGuys may be employed in addition, if desird,-*

In practice I prefer; to locate the side fenders at a point on the vesscl" ides opposite the engine and boiler room's; th;ough it is evident they may be located a i any otner desired A crane E or'sun-ilar apparatus serves to hoist and lower t,lie}bow-fenders, the suspension-ropes being fastened to eyes If, formed 12 or .'-to the hook b carried by plate I), out bothgjas desired.

' the above-described fendersit I cured, from which plate rearwardly-extending a collision will be distributed over a large surface, and much of the effect will be taken up by the elastic cushions, the result being that the injury from a collision will be greatly lessened.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A fender comprising an elastic cushion, a metallic casing therefor, an outer surrounding netting, and an elastic filling between the netting and casing, substantially as set forth.

2. A fender comprising the frame B, formed of a face-plate b, rearward-projecting diverging arms provided with suspension-eyes, and the pad secured to the said face-plate, substantially as set forth.

4. As a new article of manufacture, a fender for vessels, consisting ofa rigid frame, an elastic cushion secured thereto, and a cork facing on said cushion, substantially as described.

5. The combination, with the bow of a vessel, of a pad, and a frame carrying the pad and having diverging arms embracing the bow and movable vertically thereon and provided with guy-ropes for suspending it, substantially as set forth.

6. The combination, in a fender for vessels, of a rigid frame having rearwardly-extendin g divergent arms, an elastic cushion secured to said frame, and elastic pads secured to the arms of the said frame, substantially as de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
